Overview
The TLC5922DAPR is an LED display driver manufactured by Texas Instruments, housed in a 32-pin HTSSOP package. It features sixteen constant-current sink channels capable of delivering up to 80 mA per output. The device operates on a supply voltage ranging from 3 V to 5.5 V and supports serial communication with data transfer rates up to 30 Mbps. It includes internal dot correction for brightness uniformity and fault detection capabilities.
Feature Summary
- Integrates sixteen constant-current sink channels for high-density LED driving
- Supports high-speed serial interface for efficient data transmission
- Includes internal dot correction circuitry to ensure consistent brightness across outputs
Applications
- LED display systems requiring high channel density
- Portable electronic devices with space constraints
- General-purpose LED lighting applications
Procurement Notes
Verify the specific suffix 'RG4' against official datasheets to confirm RoHS compliance and lead time requirements. Ensure the ordering quantity aligns with manufacturer packaging standards. Confirm that the HTSSOP-32 package matches your PCB footprint design before finalizing procurement.
Selection Notes
Select this component when designing circuits that require sixteen individually controllable LED channels within a compact surface-mount package. It is suitable for applications demanding precise current control and high-speed serial data input without external components for basic operation.
Part Context
This part belongs to the TLC5922 family of LED drivers from Texas Instruments. It shares functional similarities with other members like the TLC5922DAP but differs in packaging and reel specifications. The series is designed for portable electronics where small form factors and high integration are critical.
Replacement Considerations
The TLC5922DAP is a tube-packaged equivalent offering identical electrical performance. Verify pin compatibility and thermal characteristics when substituting between reel and tube packages.
